Specification forming part of Letters Patent No. 167;,900,dated-September 21,1875japplication filed -v August 6, 1875. p

To alt whom it may concern.-

Be it known that I, GARRETT Z. HOUSE, of the city, county, and State ofNew York, have invented certain new and useful Improvements inCombination Spring-Hinges, which are set forth in the followingspecification, reference being had to the accompanying drawings, whichform a part thereof.

The object of my invention is to construct a cheap and practical hingeor butt that will swing a door both ways through the jambs or casings,and hold it closed when at rest, at the samer time swing on eachalternate corner of the casing, and attach itself firmly to the same atevery point of its swing, thus preventing danger of any settling orsagging.

The rst part of my invention consists of a double-acting spring-hinge orbutt formed of two outer plates or leaves and a sectional center-plate,divided diagonally, withV springs connecting the rst or main plate oneach edge with one end of the sectional centerplates, the other end ofthe center-plates beiEng hinged to the third plate, as shown in Thecenter sectional plate is divided diagonally, as shown in Fig. l, B B,thus forming an extended spring-joint on both sides, and attaching thesame to the first or main plate by springs in knuckles E E. Both of themainsprings of the hinge are attached to the same or main plate, and actdirectly and conjointly in holding it within the jamb in a direct line,thus ai'ording a combined supporting power of the two springs, andpreventing the door from settling or sagging.

I thus relieve the strain upon the screws and casing, and hold the doorin its place, when at rest, by the joint action of the springs, actingon both sides alike. I also obtain a large space in which to use thesprings.

The knuckles' forming the hinge connecting these plates receive thetubular pintles in which are placed the compound or combination springs.These knuckles should be exten ded on each side beyond the plates to thedis'- tance required to give strength to the springs.

The second part of my invention consists of the combination of torsionand spiral spring,

constructed vand made tol operate within the tubular pintles, as shownin Fig. 5, and these combined springs are applicable to double or singlespring-hinges. The torsion-spring I construct of two o more leavesofthin flattened steel, like a clockspring, fastened together, and madeto act within the spiral spring, the two springs being' Apassingcompletely through the spiral spring,

the outer end is attached to the ratchet-nib, as shown in Fig. 5. .Iheouter end of the spiral spring is connected by a small hook to thetubular pintle, which is connected to the sectional center-plates, andby them to the third plate, and the torsion-spring being attached by theratchet nib to the first plate, the two springs thus act together, andform a compound or combination spring, acting Within the tubular pintlein the manner above described and shown by drawings.

My combination or compound spring, thus formed, possesses the force andelasticity of the two springs combined and acting within each other. Ithus utilize my space and get double power.

This spring may be applied to all butts and hinges, both single anddouble acting. They may be removed for examination or repair byunscrewing the ratchet-nib on the outer end and withdrawing it, withoutdisturbing the action of the door.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters` Patent, s-

1. The combination and arrangement of the diagonal center-platesB B,giving an increased length of springs, and acting, by the compound orcombination springs D D, on first plate A, and, by hinge knuckles orconnectionsGG, on third plate C, forming a-hinge held at every l GARRETTZ. HOUSE. VWitnesses:
